Hi Freepine,
Thanks for the response.... i've made what you told me before, i
mean:
1) created the following modules:
- splitter node;
- recognizing plugin;
2a) created file /etc/mine_plugins_1.cfg
(0x1d4769f0,0xca0c,0x11dc,0x95,0xff,0x08,0x00,0x20,0x0c,0x9a,
0x66),"libopencorematroskarecognizer"
(0x6d3413a0,0xca0c,0x11dc,0x95,0xff,0x08,0x00,0x20,0x0c,0x9a,
0x66),"libopencorematroskarecognizer"
(0xb234567a,0xaa19,0x6e1b,
0x13,0x43,0x11,0x22,0x45,0x31,0x23,0x3b),"libopencoremkvparsernode"
2b) created file /etc/mine_plugins_2.cfg
(0x1d4769f0,0xca0c,0x11dc,0x95,0xff,0x08,0x00,0x20,0x0c,0x9a,
0x66),"libopencorematroskarecognizer.so"
(0x6d3413a0,0xca0c,0x11dc,0x95,0xff,0x08,0x00,0x20,0x0c,0x9a,
0x66),"libopencorematroskarecognizer.so"
(0xa1c9551a,0xca79,0x6e1b,0x1d,0x33,0xb1,0x12,0x33,0x3a,
0xa2,0x3f),"libopencoremkvparsernode.so"
but nothing happens... none method called from my plugins... could you
please look a little bit deeper into the code which i provided in my
previous post.

Best regards,
